Tinsley Randolph Mortimer (née Mercer; born August 11, 1975) is an American socialite and television personality.
Mortimer was born in Richmond, Virginia, where she grew up, attending St. Catherine's School. Her father was George Riley Mercer Jr., a wealthy real-estate investor, and her mother is Dale Mercer (née Tatum), an interior designer. Her paternal grandfather, George Riley Mercer Sr., founded Mercer Rug Cleansing in 1936. Mortimer is reportedly a descendant of Thomas Jefferson (on her mother's side) and a relative of Patrick Henry and James Madison (on her father's side). She grew up with one sister, Dabney Mercer. Mortimer attended the Lawrenceville School, where she was a member of the Kirby House. Though she initially chose the University of North Carolina at Chapel Hill over Columbia University, she reconsidered and left Chapel Hill to volunteer for a year at Habitat for Humanity in Washington, D.C. She reapplied and was accepted again as a freshman the following year at Columbia where she was a member of St. Anthony Hall. She graduated from Columbia with a BA in art history.
Mortimer has a line of handbags and clothing in Japan for Samantha Thavasa, for which she was featured in an advertising campaign. She also features prominently in Samantha Thavasa USA's online promotional materials and in the company's Madison Avenue store, which also carries her handbags. She subsequently formed her own clothing line, Riccime by Tinsley Mortimer, which is available in select stores in Japan, including Isetan. In 2008, Mortimer became involved in branding and design for a condominium development.
She made a cameo appearance on the season two premiere episode of Gossip Girl, which aired September 1, 2008 on The CW. On March 10, 2010, her own reality television show created by Andrew Glassman and Mike Aho for The CW called High Society, starring Mortimer along with other socialites such as Paul Johnson Calderon and Devorah Rose, first aired. The show documented the lives of Mortimer and her friends but was cancelled after eight episodes.
Mortimer wrote a novel titled Southern Charm, which follows Minty Davenport from South Carolina to New York, where she is the victim of rumors. It was published by Simon & Schuster in April 2013. Mortimer also contributed a section to the best-selling book The Park Avenue Diet  which outlined recommendations on improving one's conversation and social skills. The book was written by Manhattan diet doctor Stuart Fischer.
Mortimer met Robert Livingston "Topper" Mortimer at Lawrenceville School and eloped when they were both 18. However, their parents forced them to annul the marriage. On May 4, 2002, they remarried in Richmond, Virginia. The Mortimers are now divorced.
Her father, George, died March 26, 2015 in Providence, Rhode Island.
On February 11, 2017, Mortimer was introduced to Chicago-based, Coupon Cabin CEO, Scott Kluth, by her RHONY cast mate, Carole Radziwill. The pair continues to date long distance between New York and Chicago. As of October 2017, the couple have separated.
In April 2016, Mortimer was arrested for trespassing in Palm Beach, Florida. Police were called to a private home after reports of a woman screaming on the property. It has been reported that she was warned by authorities to cease similar behavior at the same property the year before.
